Overview
Brand Name: Huawei
Product Number: WD6M1PRU7000
Model Number: pRRU3901
Discription:
The pRRU, a remote radio unit, processes RF signals as follows:
The transmit channel receives the baseband signals from the BBU and performs
digital-to-analog conversion. The baseband signals are up-converted to the transmit
frequency band using the zero IF technology. The pRRU then filters and amplifies the
signals, which are sent to the antenna for transmission.
The receive channel receives the RF signals from the antenna. Then, the RF signals are
down-converted to baseband signals and sent to the BBU for processing after being
filtered and amplified.
pRRU3901 supports the following:
-
Built-in or external antennas
-
PoE and AC/DC adapter
-
Flexible multi-mode configurations, with built-in RF cards for multiple radio access technologies
(RATs)
-
Wi-Fi daughter cards supporting data transmission services
